Maybe the same limitation applies to 1000 km/h – which is still below Mach 1.

And finally, although there is no Concorde today, maybe Geoff will be able to fly one of these so that we will get at least past the 1000 km/h mark. ;-)

1000 km/h isn't a problem at all. All you need for that is enough tailwind. Around 100kts would be sufficient. No drama. The maximum tailwind I ever had was something like 280kts obverhead northern Labrador.
